This range of Power Wirewound Resistors are wound on continuous glass fibre elements
or have a ceramic core depending on resistance value. The element is housed in a
ceramic case and sealed with an inorganic silica filler. Their construction gives a resistor
with high insulation resistance and low surface temperature, capable of withstanding high
overload currents. These resistors are ideally suited to a variety of applications within
industrial and commercial environments, where performance and reliability are of prime
importance. Applications include fan force ovens, cooker hoods, power supplies and triac
based speed controls. Custom Design Variants in value and style are welcomed.

High Power Resistor
Type SBC (Square Ceramic) Series
Type SBC - SBCH (Axial Power Resistor)
We offer three ceramic profiles for the main wattage sizes.
These are for additional heat dissipation and vertical mounting of resistors.
The suffix for each style is as follows:-
SBC Standard
SBCH 4/5/6/7
SBCH 8/11/15
Type SBCHE (For Vertical Mounting)
We offer SBCHE Styles with one lengthened lead for vertical mounting. See additional hardware on last page.
One Lead Length 20mm longer than case length. Supplied with one longer lead wrapped back in flute in ceramic.
